You have all of this file data. It's important to your family, or your business. How do you protect it? Traditionally, you would go out and purchase an onsite NAS or some other type of hardware that would be on your network. That's great. You now have two copies of your data. But what happens if there is a fire? What happens if you have a break in, and your laptops and NAS are all stolen? How do you get that data back?
With the rise of cheap and secure cloud based storage, especially Cloud Storage via Amazon S3, getting that data offsite may be easier than you think. From a family standpoint, most of your standard NAS services include a vaulting to S3 or Glacier software package. If not, you can utilize the web interface or API for driving your data to S3 or Glacier.
Amazon also has their Virtual Storage Gateway software appliance. The usage cost of $125/mo may be a bit high for a family, but could be perfect for a small to medium sized business. There are also other methods of getting data into s3 via the AWS API's and the robust AWS CLI application. I will do future posts on those options.
Here's an architectural layout on how the Storage Gateway VM works.
